RIM announces Q4 2012 earnings, Jim Balsillie resigns from board

Engadget - We've already seen a bit of big news slip out ahead of RIM's earnings announcement, and the company's now dropped another bombshell itself. Former co-CEO Jim Balsillie has resigned from his position on the company's board of directors. In a statement, Balsillie said simply: "As I complete my retirement from RIM, I'm grateful for this remarkable experience and for the opportunity to have worked with outstanding professionals who helped turn a Canadian idea into a global success." RIM also confirmed that CTO David Yach would be retiring as well, and that COO Jim Rowan has "decided to pursue other interests," but it hasn't offered any indication of a broader shakeup beyond those three departures.
